Canola is not the name of a natural plant but a made-up word, from the words “CANadian Oil Low Acid”. Canola is a genetically engineered plant developed in Canada from the Rapeseed Plant, which is part of the mustard family of plants. According to AgriAlternatives, The Online Innovation, and Technology Magazine for Farmers, “By nature, these rapeseed oils, which have long been used to produce oils for industrial purposes, are… toxic to humans and other animals”.
Rapeseed oil is poisonous to living things and is an excellent insect repellent. I have been using it (in very diluted form, as per instructions) to kill the aphids on my roses for the last two years. It works very well; it suffocates them. Ask for it at your nursery. Rape is an oil that is used as a lubricant, fuel, soap and synthetic rubber base and as a illuminate for color pages in magazines. It is an industrial oil.
It is not a food.
Rape oil is strongly related to symptoms of emphysema, respiratory distress, anemia, constipation, irritability, and blindness in animals and humans.
